The Late Heavy Bombardment (commonly referred to as the lunar cataclysm, or LHB) is a period of time approximately 4.1 to 3.8 billion years ago during which a large number of impact craters are believed to have formed on the Moon, and by inference on Earth, Mercury, Venus, and Mars as well. Late Heavy Bombardment. The new study estimates the thermal effects of a period known as the Late Heavy Bombardment (LHB) on Earth. The answer may lie with comets.

Such a thing likely occurred on Earth about 4 billion years ago. By inference the same thing happened on Earth, Mercury, Venus, and Mars as well. The conventional idea is that the LHBP occurred 4.1 to 3.8 billion years ago. “There’s no question that something has happened in the past few years that has profoundly upset the apple cart. Space debris pelted Earth in the late heavy bombardment stage (LHB) about 4 billion years ago in the Hadean Eon.

The Late Heavy Bombardment refers to impact events that occurred after stabilization of the planetary lithospheres such that they could be preserved as craters and basins.
The Late Heavy Bombardment (LHB) (Wetherill 1975) has been a central concept in planetary sciences since the 1960s, following detailed geological observations of the Moon and the discovery of petrological and geochemical evidence for intense shock metamorphism at ∼3.9 Ga in many of the Apollo missions’ lunar samples (Stöffler et al.

The evidence of this pummeling is clear to see in the maria basins on the Moon and in similar structures elsewhere, such as the Caloris Basin on Mercury and the great craters in the southern hemisphere of Mars. Life itself was formed either a few dozen million years before the late heavy bombardment or near its conclusion.
